Deterministic Signal : Deterministic signal refers to the signal about which there exists no certainty with respect to its value at any time. Consequently, deterministic signals can also be modelled as completely specified functions of the time.

Random signal : Random signal refers to the signal about which there exists uncertainty before its actual occurrence. Such type of signal can be viewed as the group of signals with every signal within the ensemble which is having different wave forms. For example: the noise within the television or radio amplifier is an example of random signal.
